Description
Single-row tapered roller bearing of separable design: the inner ring with the roller and cage assembly is handled independently of the outer ring. Main dimensions comply with DIN 720. Bore diameter is 55 mm, outside diameter 120 mm, the bearing is fitted with a standard cage and its net mass is 1.57 kg. The limiting speed is 5900 1/min. The tapered raceways take radial load combined with axial load acting in one direction, so the bearing is set against a second bearing in an opposed arrangement, with the operating clearance obtained by axial adjustment during assembly. Separability allows each ring to be mounted on its seat individually and makes dismounting easier; the 5900 1/min value is the upper speed limit for operation.
